Patented Nov. 6, 1934 UNITED STATES F FIC E CLICK LOCK Alexander Enos,New York, N. Y.

My invention relates to looks and refers more particularlyto clicklocks.

One object of my invention is to provide a click 3 v padlock, having ashackle, with a locking pin that prevents the shackle from beingwithdrawn from the lock body or cylinder until the said pin is movedintoithe inoperative position, which pin is also utilized for lockingthe plunger of the clicking mechanism so as to prevent it beingwithdrawn and movably holding it in its operating position.

Another object feature of my invention is to provide a click lock havingacylinder carrying acentrally arranged operating ring cooperating withtwo locking rings on each side thereof, said cylinder providedwith pinsadapted to detachably hold two end caps thereto and to prevent themovement of the end capswhen the shackle is removed and toprevent thecaps from turning whena new combination is being tested, or tried out.

One valuable object of my invention is to provide a click padlockcomprised of a cylinder carrying a centrally arranged operating ringcooperating with two oppositely arranged locking rings,

numerals refer to like parts throughout the several views, inwhich:

Figure 12 is an assembly of the lock partly in section.

Figure 13 is an elevation of one of the L shaped blocks with apintherein.

Thelock includes a cylinder 1, with rounded ends 2 and 3, and throughshackle holes 4 and 5. In the center of this cylinder is a hole carryinga plunger 6," and a plunger spring '7, and this plunger isnotchedat: 8to hold apin 9, provided with a head 10, so that when the pin ispositioned,

as shown inFigure '12, the end of this pin will enter into a slot on oneleg of the shackle, hereinafter referred to, and thereis a notch13,sforthe head 10 to enter into=when the pin is positioned'as shown inFigure12.

"On each end of this cylinder there are notches 14 and lfiior holdingthe heads 16 and 17 ofithe -pins 1 8 and 19, the object of thesepinsbeing to lock the caps one of which is shown in Figures 1 8 and-9,from moving when the shackle 20 is removed from the lock and also toprevent the caps from turning when the combination is being tested butwhen the combination is to be changed,

these pinsare raised up by pulling the: heads 16 and 1'] upwardly.

Overthis cylinderd, the operating ring21, is positioned between theshackle holes 4 and 5, the

inside of thering having a large notch 22 which functions as a startingspace in the operation of the lock and there are a plurality of smallerslots 23, for engaging with the end of the plunger'fi,

so that when this ring is moved, theplunger action" due' to the spring7, will cause a click to be felt or heard.

The central portion of the'slots 23 of the ring 21' is acted upon by theplunger 6, as aforesaid,

and the remaining portion of each slot not taken up bythe plungeraction, is adapted to'hold and seat'an L shaped block25, which ispreferably provided with a pin 26. In ring 21 radially opposite each oneof these small slots 23 is ahole 24 into "which pin 26 fits, whenpositioned for use. :There are two blocks 25'1ocated on the ring 21, oneon each side of said ring.

Adjacent the outer edge of this ring 21, are twogrooves 2'7 and 28, thatengage with the flange 29 of the end blocks, one of which is shown inFigures 8 and 9, and the extreme outer surface of this ring isknurled,as shown in Figure '7 by 30 so that the fingers of the operator may havea grip for turning the ring. 7

The end rings or caps 31, are'flanged at 29, as hereinbefore referredto,and for the purposes stated, and provided with a hole 32 to fit thecylinder 1.

The end of these caps is rounded at 33, to register with the ends 2 and3 of the cylinder when the caps are positioned as clearly shown inFigure 12.

These caps are also provided with shackle holes, one of which is shownin Figures 8 and 9 by 34 and a hole 35 to receive the end of the pins 18and 19 respectively.

In the space 36 provided when the ends are in position, the lockingrings, one of which is shown in Figures 10 and 11, are rotatablymounted, so that the surface 37 of the rings are spaced near thesurfaces 38 and 39, respectively of the ring 21, thus leaving a spacefor the movement of the L shaped blocks 25 therein.

It is obvious when aforesaid L shaped blocks are placed in differentslots in the operating ring 21, with the blocks projecting on each sideof the ring, they are adapted to come in contact with similar blocks inthe locking rings 41. Two blocks 25, are placed in the slots 40 of eachring 41, and it is obvious that these blocks will interengage with theblocks 25 located in the operating ring 21 so that when the operatingring is moved, the locking rings will be moved a distance dependent upontheir relative positions, whereby it is clear that by relocating theseblocks, almost any combination may be obtained for the lock.

When the operating ring carrying a projecting block on each side ismoved in either direction, these blocks come in contact with otherblocks mounted on the locking ring 21, so that the locking rings will bemoved, thus moving the openings 42 around into alignment with the slots43 and 44 respectively, in the shackle 20 and when these holes registerwith the body of the shackle, the shackle can be moved and the lockLlIllOCkBd.

The blocks 25 are adapted to be fitted into and seated within the slots40, of the locking rings 41 and the pin 26, if used is formed to fitinto the hole 45 if used therein and also into the slots 23 and holes 24if used, of the operating ring but the pins 26 and holes 24 and 45 arenot absolutely necessary elements of the lock as it will operate withoutthem.

One side of the shackle 20 is shouldered at 46, and has a portion 4'7that can enter into the hole 5 of the shackle and a notch 43, forallowing the movement therein of the locking ring, as hereinbeforestated, and this notch 43 is provided with a rib or tooth 48, that isformed to enter into the grooves 40 if the shackle is moved outwardly,so that in this event, the lock will be deadlocked and all furthermovement of the locking rings prevented.

The other side of the shackle 20 is shouldered at 49, has a notch 44,registered with and facing the notch 43 and a rib of tooth 50, whichserves for the same purpose as the rib or tooth 48 for the oppositelocking ring.

This leg of the shackle is extended at 51 and has a groove 52, at itsend and has a notch 53, cut therein with one end in spaced relation tothe notch 44 and the other end terminating in the groove 52.

The object of this groove 52 is to prevent the complete withdrawal ofthe shackle 20 from the look when the shackle is open which withdrawalis prevented by the pin 9, as clearly shown in Figure 12, and when it isdesired to change the combination, the shackle can be removed by movingthe pin 9, and the caps moved by moving the pins 18 and 19, thusallowing the whole lock to be dismantled and a new combination set.

The short leg of the shackle is bevelled at 54,

so that when the combination has been changed and the shackle positionedfor use, the bevelled part 54 will force the head 10 of the pin 9, intothe locking position, as clearly shown in Figure 12, whereby the longleg of the shackle will be prevented from leaving the cylinder.

Having thus illustrated and described the preferred embodiment of myinvention, I do not wish to limit myself to the exact construction orarrangement of parts shown, since it is evident that modifications maybe made therein without departing from the spirit of the invention orscope of the claims.
